Oil seals are commonly used in driveshafts, crankshafts and hydraulic cylinders where a rotating shaft is lubricated by oil or grease. The seal works like a cap, covering the clearance between the shaft and housing, stopping fluids from leaking whilst preventing containments from entering the chamber. If you are replacing a worn part because you have identified a leak, refer to your machinery handbook to find the type of oil seal you require. Whilst this is not always possible there are a few guidelines to help you get the right seal for the job.
